IMPROVEIVIENT IN HARVE STER FINGER-GUARDS.

Specification forming pzut of Letters Patent N0. 212,637, dafud February 25, 1879 application fi1ed Januzuy .9, 1879.

T0 all whom z't may concem:

Be it known that I, JAMES M. WEAVER, 0f Seenery Hill, in the county 0f Washington and State 0f Pennsylvania, have invented certain 11 ew and useful Im provem ents in Finger-Gu ards for Harveste1s, 01 Whieh the following is 211 full, dem, and exact deseription, such as will enable others skilled. in the art to which ib perta-ins t0 make am]. use it referenee being had to the aeeompanying drawings, which forma a art of this specification.

My invention rlates t0 an improvement in finger-guards for harvesters.

lt is well known tha t in the operation of t11e harvester the lower portion 01 shank of the finger-guard becomes worn by reason 0f its frietional contact With the knives, and the guard is consequenuly s0011 nmterially impaired, its effeotive operatiou prevented, and it must soon be replaced by a new one.

'lhe obj eeb of my inventiou is 110 so construct the guarcl thal: its eutting surface may be sharpened and re-edged, and thus obviate the seri0us defeeo in these guards, as above mehc-ioned.

Referring to ehe drawings, Figure 1 represents a longitudinal vertieal section of a fingerguard for harvesters construeted in aecordance With my invention. Fig. 2 shows a side elevation 0f the guard with the parts separated.

A represents the shank, and B the combined point and t0p portion, ofthe guard. The arts A and B are connected together by a tongueand-groove connection and 0ne er more screws 0r bolts.

Ib will be observed that by this construetion ehe point and upper portion of the guard are formed in 0ne piece, am]. are securely connected. with the shauk A; and. the guard is thus formed es eompaetly and reliably as ifthe same were made 0f a single pieee 0f material.

Another obvious advantage arising from n1y novel construction 0f finger-guardis, filmt while ehe cutting portion of t-l1e same is preferably made of steel, t11e point and portion B may be of castiron, and. the cost of manufacture is thus materially lessened.

Having ful1y deseribed my invention, what I c1aim, and desire t0 secure by Letters Patent, is-

A harvester fiuger guard formedl of tw0 parts, fastened together by tongue-and-groove engagement and one 0r more screws, the lower portion having its forw-ard end cut oft a1; an acute angle ancl abuttiug against a s houlder 011 the upper portion, substantially as described.

In testimony that I claim the foregoing I hzwe hereunto set my band this 23d. day of December, A. D. 1878.
